We are trying to determine if we can use ReportViewer to access the Reporting Services in our secure environment.

We have
-SQL server 2008 with Reporting Services installed(no Sharepoint Integration). 
-ReportViewer control running in a WPF application.  

To access the Reporting Services we have to traverse a Micrsoft ISA server with a X509 certificate. The ISA server then translates the X509 cert into the users window credentials.  

I can create a service reference and embed the certificate in the transport credentials but I don't know how to get the ReportViewer control to use this service reference.

Any ideas?
